Title: Dynamic logic circuit
Inventor: TAGUCHI MASAO
IPC: H03K19/096
Filed: 1985-05-20
Abstract: PURPOSE:To obtain a dynamic logic circuit with low manufacture cost advantageous to circuit integration by precharging an output terminal in advance and activating a sense circuit after the input logic state is confirmed to obtain an output potential in response to the input logic state. CONSTITUTION:In bringing a precharge clock phiP to an H level and input logic states A, A', B, B' to an H level, then output nodes N1, N2 go both to an H level. Then the input logic state is confirmed at a time t0 and the clock phiP is brought into L level at a time t1. In bringing the activated clock phiA from L to H level at a time t2, the operation of a sense circuit [consisting of transistors (TRs) Q19, Q20] is started. In selecting the A to the H level and the B to the L level, for example, a node N1 goes to an H level and a node N2 goes to an L level, and the TR Q19 is turned off. In bringing both the A, B to the H level, the node N2 goes to H level and the node N1 goes to L level, and the TR Q20 is turned off. Thus, a potential difference is caused between the nodes N1 and N2 and an exclusive OR (A+B), (A+B)' are obtained respectively from the nodes N1, N2.

Filed: 1980-07-31
Abstract: PURPOSE:To form a continuously and easily a multilayer thin film having different kinds of compositions in a magnetic gap by dividing a target electrode into a plurality of faces having different material compositions and by alternately covering the divided faces with a shielding plate having the same shape as each of the divided faces. CONSTITUTION:A target electrode 1 is formed into a disk or the like and divided into target faces having different material compositions 3, 4 in the radius direction. A shielding plate 2 having the same shape as each of the divided faces such as a semicircular plate is first set over the composition 3 part, and by carrying out sputtering and vapor deposition, discharge for sputtering is caused on the electrode 1 at the composition 4 part alone to form a sputtered coat of the composition 4 alone. By rotating the plate 2 by 180 deg., the discharge from the composition 4 part is  stopped, and discharge is caused on the electrode 1 at the composition 3 part. Thus, the coat of the composition 4 is coated with the composition 3 without mixing the material to form a continuous film. This method is effective in working a magnetic gap used to form a magnetic head of high accuracy.

The heat pipe is used with its heat absorbing part 1b directing downward and its condensate part 1a upward. When the operating liquid 3 is evaporated in the heat absorbing part 1b, the operating liquid in the capillary tube 4 is also evaporated to increase the internal pressure. Accordingly, the steam is discharged into the operating liquid 3 as air bubbles from the open end, the internal pressure in the heat absorbing part 1b rises to produce difference in pressure of the condensate part 1a, and it brings the heat pipe into starting. Thus, the starting property of heat pipe at the time of low absorbing rate of heat can be improved.
